TLDR:

git pull is like running git fetch then git merge
git pull --rebase is like git fetch then git rebase

In reply to your first statement,

git pull is like a git fetch + git merge.

"In its default mode, git pull is shorthand for git fetch followed by git merge FETCH_HEAD" More precisely, git pull runs git fetch with the given parameters and then calls git merge to merge the retrieved branch heads into the current branch"

(Ref: https://git-scm.com/docs/git-pull)

For your second statement/question:

'But what is the difference between git pull VS git fetch + git rebase'

Again, from same source:
git pull --rebase

"With --rebase, it runs git rebase instead of git merge."

Now, if you wanted to ask

'the difference between merge and rebase'

that is answered here too:
https://git-scm.com/book/en/v2/Git-Branching-Rebasing
(the difference between altering the way version history is recorded)

Another way to look at it is to consider git rebase master as:

Rebase the current branch on top of master

Here , 'master' is the upstream branch, and that explain why, during a rebase, ours and theirs are reversed.

Merge squash merges a tree (a sequence of commits) into a single commit. That is, it squashes all changes made in n commits into a single commit.

Rebasing is re-basing, that is, choosing a new base (parent commit) for a tree. Maybe the mercurial term for this is more clear: they call it transplant because it's just that: picking a new ground (parent commit, root) for a tree.

When doing an interactive rebase, you're given the option to either squash, pick, edit or skip the commits you are going to rebase.

Hope that was clear!

Here's a script that will allow you to cherry-pick multiple commits in a row simply by telling the script which source and target branches for the cherry picks and the number of commits:

https://gist.github.com/nickboldt/99ac1dc4eb4c9ff003a1effef2eb2d81

To cherry-pick from your branch to master (uses the current branch as source):

./gcpl.sh -m

To cherry-pick the latest 5 commits from your 6.19.x branch to master:

./gcpl.sh -c 5 -s 6.19.x -t master

Adding to the answers using --onto:

I never learned it by heart, so I wrote this little helper script:
Git: Rebase a (sub)branch from one base to another, leaving the other base's commits.

Usage:

moveBranch <branch> from <previous-base> to <new-base>

In short:

git rebase --onto "$3" "$2" "$1"

Besides that, one more solution usable for similar purposes, is cherry-picking a streak of commits:

git co <new-base> 
git cherry-pick <previous-base>..<branch>
git branch -f branch

Which has more less the same effect. Note that this syntax SKIPS the commit at <previous-branch> itself, so it cherry-picks the next and the following up to, including, the commit at <branch>.

I got this error when my VS1013 was on a branch targeting 8.1 and I was trying to checkout a 8.0 branch. I needed to tab back to VS and allow it to UpdateAll. Then I could checkout the 8.0 branch without error.

This will remove it from your history

git filter-branch --force --index-filter 'git rm -r --cached --ignore-unmatch bigfile.txt' --prune-empty --tag-name-filter cat -- --all

Note: if you were on Branch1, you will with Git 2.0 (Q2 2014) be able to type:

git checkout Branch2
git rebase -

See commit 4f40740 by Brian Gesiak modocache:

rebase: allow "-" short-hand for the previous branch

Teach rebase the same shorthand as checkout and merge to name the branch to rebase the current branch on; that is, that "-" means "the branch we were previously on".

• From your merge commit
• Cherry-pick the new change which should be easy
• copy your stuff
• redo the merge and resolve the conflicts by just copying the files from your local copy ;)

git reset --hard commitId

git push <origin> <branch> --force

PS: CommitId refers the one which you want to revert back to

Use these 4 simple commands

Step 1 : git checkout <branch_name>

This is obvious to go into that branch.

Step 2 : git pull -s recursive -X theirs

Take remote branch changes and replace with their changes if conflict arise. Here if you do git status you will get something like this your branch is ahead of 'origin/master' by 3 commits.

Step 3 : git reset --hard origin/<branch_name>

Step 4 : git fetch

Hard reset your branch.

Enjoy.

If you are here to copy-paste code:

This is an example which removes node_modules from history

git filter-branch --tree-filter "rm -rf node_modules" --prune-empty HEAD
git for-each-ref --format="%(refname)" refs/original/ | xargs -n 1 git update-ref -d
echo node_modules/ >> .gitignore
git add .gitignore
git commit -m 'Removing node_modules from git history'
git gc
git push origin master --force

What git actually does:

The first line iterates through all references on the same tree (--tree-filter) as HEAD (your current branch), running the command rm -rf node_modules. This command deletes the node_modules folder (-r, without -r, rm won't delete folders), with no prompt given to the user (-f). The added --prune-empty deletes useless (not changing anything) commits recursively.

The second line deletes the reference to that old branch.

The rest of the commands are relatively straightforward.

Here's a better option:

git remote set-head -a origin

From the documentation:

With -a, the remote is queried to determine its HEAD, then $GIT_DIR/remotes//HEAD is set to the same branch. e.g., if the remote HEAD is pointed at next, "git remote set-head origin -a" will set $GIT_DIR/refs/remotes/origin/HEAD to refs/remotes/origin/next. This will only work if refs/remotes/origin/next already exists; if not it must be fetched first.

This has actually been around quite a while (since v1.6.3); not sure how I missed it!

When you have a conflict during rebase you have three options:

• You can run git rebase --abort to completely undo the rebase. Git will return you to your branch's state as it was before git rebase was called.

• You can run git rebase --skip to completely skip the commit. That means that none of the changes introduced by the problematic commit will be included. It is very rare that you would choose this option.

• You can fix the conflict as iltempo said. When you're finished, you'll need to call git rebase --continue. My mergetool is kdiff3 but there are many more which you can use to solve conflicts. You only need to set your merge tool in git's settings so it can be invoked when you call git mergetool https://git-scm.com/docs/git-mergetool

If none of the above works for you, then go for a walk and try again :)

Resetting the branch to the dangling commit object of its old tip is of course the best solution, because it restores the previous state without expending any effort. But if you happen to have lost those commits (f.ex. because you garbage-collected your repository in the meantime, or this is a fresh clone), you can always rebase the branch again. The key to this is the --onto switch.

Let’s say you had a topic branch imaginatively called topic, that you branched off master when the tip of master was the 0deadbeef commit. At some point while on the topic branch, you did git rebase master. Now you want to undo this. Here’s how:

git rebase --onto 0deadbeef master topic

This will take all commits on topic that aren’t on master and replay them on top of 0deadbeef.

With --onto, you can rearrange your history into pretty much any shape whatsoever.

Have fun. :-)

1.Update Master first...

git checkout [master branch]
git pull [master branch]

2.Now rebase source-branch with master branch

git checkout [source branch]
git rebase [master branch]
git pull [source branch] (remote/source branch)
git push [source branch]

IF source branch does not yet exist on remote then do:

git push -u origin [source branch]

"et voila..."

If all you want to do is squash all of your commits down to the root commit, then while

git rebase --interactive --root

can work, it's impractical for a large number of commits (for example, hundreds of commits), because the rebase operation will probably run very slowly to generate the interactive rebase editor commit list, as well as run the rebase itself.

Here are two quicker and more efficient solutions when you're squashing a large number of commits:

Alternative solution #1: orphan branches

You can simply create a new orphan branch at the tip (i.e. the most recent commit) of your current branch. This orphan branch forms the initial root commit of an entirely new and separate commit history tree, which is effectively equivalent to squashing all of your commits:

git checkout --orphan new-master master
git commit -m "Enter commit message for your new initial commit"

# Overwrite the old master branch reference with the new one
git branch -M new-master master

Documentation:

• git-checkout(1) Manual Page.

Alternative solution #2: soft reset

Another efficient solution is to simply use a mixed or soft reset to the root commit <root>:

git branch beforeReset

git reset --soft <root>
git commit --amend

# Verify that the new amended root is no different
# from the previous branch state
git diff beforeReset

Documentation:

• git-reset(1) Manual Page.

To complement my own answer mentioned by TSamper,

• a rebase is quite often a good idea to do before a merge, because the idea is that you integrate in your branch Y the work of the branch B upon which you will merge.
  But again, before merging, you resolve any conflict in your branch (i.e.: "rebase", as in "replay my work in my branch starting from a recent point from the branch B).
  If done correctly, the subsequent merge from your branch to branch B can be fast-forward.

• a merge directly impacts the destination branch B, which means the merges better be trivial, otherwise that branch B can be long to get back to a stable state (time for you solve all the conflicts)

the point of merging after a rebase?

In the case that I describe, I rebase B onto my branch, just to have the opportunity to replay my work from a more recent point from B, but while staying into my branch.
In this case, a merge is still needed to bring my "replayed" work onto B.

The other scenario (described in Git Ready for instance), is to bring your work directly in B through a rebase (which does conserve all your nice commits, or even give you the opportunity to re-order them through an interactive rebase).
In that case (where you rebase while being in the B branch), you are right: no further merge is needed:

A Git tree at default when we have not merged nor rebased

we get by rebasing:

That second scenario is all about: how do I get new-feature back into master.

My point, by describing the first rebase scenario, is to remind everyone that a rebase can also be used as a preliminary step to that (that being "get new-feature back into master").
You can use rebase to first bring master "in" the new-feature branch: the rebase will replay new-feature commits from the HEAD master, but still in the new-feature branch, effectively moving your branch starting point from an old master commit to HEAD-master.
That allows you to resolve any conflicts in your branch (meaning, in isolation, while allowing master to continue to evolve in parallel if your conflict resolution stage takes too long).
Then you can switch to master and merge new-feature (or rebase new-feature onto master if you want to preserve commits done in your new-feature branch).

So:

• "rebase vs. merge" can be viewed as two ways to import a work on, say, master.
• But "rebase then merge" can be a valid workflow to first resolve conflict in isolation, then bring back your work.

While the accepted and most upvoted answer is great, I additionally find it useful trying to explain the difference only by words:

merge

• “okay, we got two differently developed states of our repository. Let's merge them together. Two parents, one resulting child.”

rebase

• “Give the changes of the main branch (whatever its name) to my feature branch. Do so by pretending my feature work started later, in fact on the current state of the main branch.”
• “Rewrite the history of my changes to reflect that.” (need to force-push them, because normally versioning is all about not tampering with given history)
• “Likely —if the changes I raked in have little to do with my work— history actually won't change much, if I look at my commits diff by diff (you may also think of ‘patches’).“

summary: When possible, rebase is almost always better. Making re-integration into the main branch easier.

Because? ? your feature work can be presented as one big ‘patch file’ (aka diff) in respect to the main branch, not having to ‘explain’ multiple parents: At least two, coming from one merge, but likely many more, if there were several merges. Unlike merges, multiple rebases do not add up. (another big plus)

Here's a very nice Gist that covers all the possible cases: https://gist.github.com/nepsilon/156387acf9e1e72d48fa35c4fabef0b4

Overview:

git rebase -i HEAD~X
# X is the number of commits to go back
# Move to the line of your commit, change pick into edit,
# then change your commit message:
git commit --amend
# Finish the rebase with:
git rebase --continue

Mine was an error that popped up from BitBucket. Ran git am --skip fixed it.

Had same problem in Eclipse. Could not Rebase=>abort from Eclipse.

Executing git rebase --abort from Git Bash Worked for me.

Update July 2012 (git 1.7.12+)

You now can rebase all commits up to root, and select the second commit Y to be squashed with the first X.

git rebase -i --root master

pick sha1 X
squash sha1 Y
pick sha1 Z

git rebase [-i] --root $tip

This command can now be used to rewrite all the history leading from "$tip" down to the root commit.

See commit df5df20c1308f936ea542c86df1e9c6974168472 on GitHub from Chris Webb (arachsys).

Original answer (February 2009)

I believe you will find different recipes for that in the SO question "How do I combine the first two commits of a git repository?"

Charles Bailey provided there the most detailed answer, reminding us that a commit is a full tree (not just diffs from a previous states).
And here the old commit (the "initial commit") and the new commit (result of the squashing) will have no common ancestor.
That mean you can not "commit --amend" the initial commit into new one, and then rebase onto the new initial commit the history of the previous initial commit (lots of conflicts)

(That last sentence is no longer true with git rebase -i --root <aBranch>)

Rather (with A the original "initial commit", and B a subsequent commit needed to be squashed into the initial one):

1. Go back to the last commit that we want to form the initial commit (detach HEAD):

   git checkout <sha1_for_B>
   

2. Reset the branch pointer to the initial commit, but leaving the index and working tree intact:

   git reset --soft <sha1_for_A>
   

3. Amend the initial tree using the tree from 'B':

   git commit --amend
   

4. Temporarily tag this new initial commit (or you could remember the new commit sha1 manually):

   git tag tmp
   

5. Go back to the original branch (assume master for this example):

   git checkout master
   

6. Replay all the commits after B onto the new initial commit:

   git rebase --onto tmp <sha1_for_B>
   

7. Remove the temporary tag:

   git tag -d tmp
   

That way, the "rebase --onto" does not introduce conflicts during the merge, since it rebases history made after the last commit (B) to be squashed into the initial one (which was A) to tmp (representing the squashed new initial commit): trivial fast-forward merges only.

That works for "A-B", but also "A-...-...-...-B" (any number of commits can be squashed into the initial one this way)

If you want to pull a particular file from another branch just do

git checkout branch1 -- filenamefoo.txt

This will pull a version of the file from one branch into the current tree

For each conflicted file you get, you can specify

git checkout --ours -- <paths>
# or
git checkout --theirs -- <paths>

From the git checkout docs

git checkout [-f|--ours|--theirs|-m|--conflict=<style>] [<tree-ish>] [--] <paths>...

--ours
--theirs
When checking out paths from the index, check out stage #2 (ours) or #3 (theirs) for unmerged paths.

The index may contain unmerged entries because of a previous failed merge. By default, if you try to check out such an entry from the index, the checkout operation will fail and nothing will be checked out. Using -f will ignore these unmerged entries. The contents from a specific side of the merge can be checked out of the index by using --ours or --theirs. With -m, changes made to the working tree file can be discarded to re-create the original conflicted merge result.

"Even if you’re a single developer with only a few branches, it’s worth it to get in the habit of using rebase and merge properly. The basic work pattern will look like:

• Create new branch B from existing branch A

• Add/commit changes on branch B

• Rebase updates from branch A

• Merge changes from branch B onto branch A"

https://www.atlassian.com/git/tutorials/merging-vs-rebasing/

There are two ways to tackle this based on what you want:

Solution 1: Remove purple commits, preserving history (incase you want to roll back)

git revert -m 1 <SHA of merge>

-m 1 specifies which parent line to choose

Purple commits will still be there in history but since you have reverted, you will not see code from those commits.

Solution 2: Completely remove purple commits (disruptive change if repo is shared)

git rebase -i <SHA before branching out>

and delete (remove lines) corresponding to purple commits.

This would be less tricky if commits were not made after merge. Additional commits increase the chance of conflicts during revert/rebase.

Interestingly, the HttpWebResponse.GetResponseStream() that you get from the WebException.Response is not the same as the response stream that you would have received from server. In our environment, we're losing actual server responses when a 400 HTTP status code is returned back to the client using the HttpWebRequest/HttpWebResponse objects. From what we've seen, the response stream associated with the WebException's HttpWebResponse is generated at the client and does not include any of the response body from the server. Very frustrating, as we want to message back to the client the reason for the bad request.

I use this solution:

It's a bit more concise since I use: ng-repeat="obj in objects | filter : paginate" to filter the rows. Also made it working with $resource:

If the array is unsorted, you will need to use linear search.

How about:

    For Each oSheet In ActiveWorkbook.Sheets
        If oSheet.ListObjects.Count > 0 Then
          oCmbBox.AddItem oSheet.Name
        End If
    Next oSheet

You can try ironJS, looks promising although it is in heavy development. https://github.com/fholm/IronJS

If you are using httpclient 4.2, then you need to write a small bit of extra code. I wanted to be able to customize both the "TLS enabled protocols" (e.g. TLSv1.1 specifically, and neither TLSv1 nor TLSv1.2) as well as the cipher suites.

public class CustomizedSSLSocketFactory
    extends SSLSocketFactory
{
    private String[] _tlsProtocols;
    private String[] _tlsCipherSuites;

    public CustomizedSSLSocketFactory(SSLContext sslContext,
                                      X509HostnameVerifier hostnameVerifier,
                                      String[] tlsProtocols,
                                      String[] cipherSuites)
    {
        super(sslContext, hostnameVerifier);

        if(null != tlsProtocols)
            _tlsProtocols = tlsProtocols;
        if(null != cipherSuites)
            _tlsCipherSuites = cipherSuites;
    }

    @Override
    protected void prepareSocket(SSLSocket socket)
    {
        // Enforce client-specified protocols or cipher suites
        if(null != _tlsProtocols)
            socket.setEnabledProtocols(_tlsProtocols);

        if(null != _tlsCipherSuites)
            socket.setEnabledCipherSuites(_tlsCipherSuites);
    }
}

Then:

    SSLContext sslContext = SSLContext.getInstance("TLS");

    sslContext.init(null, getTrustManagers(), new SecureRandom());

    // NOTE: not javax.net.SSLSocketFactory
    SSLSocketFactory sf = new CustomizedSSLSocketFactory(sslContext,
                                                         null,
                                                         [TLS protocols],
                                                         [TLS cipher suites]);

    Scheme httpsScheme = new Scheme("https", 443, sf);
    SchemeRegistry schemeRegistry = new SchemeRegistry();
    schemeRegistry.register(httpsScheme);

    ConnectionManager cm = new BasicClientConnectionManager(schemeRegistry);

    HttpClient client = new DefaultHttpClient(cmgr);
    ...

You may be able to do this with slightly less code, but I mostly copy/pasted from a custom component where it made sense to build-up the objects in the way shown above.

do.call(rbind, lapply(split(group,as.factor(group$Subject)), function(x) {return(x[which.max(x$pt),])}))

Using Base R

I have used Open source Web Design in the past. They have quite a few css themes, don't know about ASP.Net

The only secure way of doing this

The only guaranteed secure method of retrieving the current domain is to store it in a secure location yourself.

Most frameworks take care of storing the domain for you, so you will want to consult the documentation for your particular framework. If you're not using a framework, consider storing the domain in one of the following places:

The following work... but they're not secure

Hackers can make the following variables output whatever domain they want. This can lead to cache poisoning and barely noticeable phishing attacks.

$_SERVER['HTTP_HOST']

This gets the domain from the request headers which are open to manipulation by hackers. Same with:

$_SERVER['SERVER_NAME']

This one can be made better if the Apache setting usecanonicalname is turned off; in which case $_SERVER['SERVER_NAME'] will no longer be allowed to be populated with arbitrary values and will be secure. This is, however, non-default and not as common of a setup.

In popular systems

Below is how you can get the current domain in the following frameworks/systems:

WordPress

$urlparts = parse_url(home_url());
$domain = $urlparts['host'];

If you're constructing a URL in WordPress, just use home_url or site_url, or any of the other URL functions.

Laravel

request()->getHost()

The request()->getHost function is inherited from Symfony, and has been secure since the 2013 CVE-2013-4752 was patched.

Drupal

The installer does not yet take care of making this secure (issue #2404259). But in Drupal 8 there is documentation you can you can follow at Trusted Host Settings to secure your Drupal installation after which the following can be used:

\Drupal::request()->getHost();

Other frameworks

Feel free to edit this answer to include how to get the current domain in your favorite framework. When doing so, please include a link to the relevant source code or to anything else that would help me verify that the framework is doing things securely.

Addendum

Exploitation examples:

1. Cache poisoning can happen if a botnet continuously requests a page using the wrong hosts header. The resulting HTML will then include links to the attackers website where they can phish your users. At first the malicious links will only be sent back to the hacker, but if the hacker does enough requests, the malicious version of the page will end up in your cache where it will be distributed to other users.

2. A phishing attack can happen if you store links in the database based on the hosts header. For example, let say you store the absolute URL to a user's profiles on a forum. By using the wrong header, a hacker could get anyone who clicks on their profile link to be sent a phishing site.

3. Password reset poisoning can happen if a hacker uses a malicious hosts header when filling out the password reset form for a different user. That user will then get an email containing a password reset link that leads to a phishing site. Another more complex form of this skips the user having to do anything by getting the email to bounce and resend to one of the hacker's SMTP servers (for example CVE-2017-8295.)

4. Here are some more malicious examples

Additional Caveats and Notes:

• When usecanonicalname is turned off the $_SERVER['SERVER_NAME'] is populated with the same header $_SERVER['HTTP_HOST'] would have used anyways (plus the port). This is Apache's default setup. If you or devops turns this on then you're okay -- ish -- but do you really want to rely on a separate team, or yourself three years in the future, to keep what would appear to be a minor configuration at a non-default value? Even though this makes things secure, I would caution against relying on this setup.
• Redhat, however, does turn usecanonical on by default [source].
• If serverAlias is used in the virtual hosts entry, and the aliased domain is requested, $_SERVER['SERVER_NAME'] will not return the current domain, but will return the value of the serverName directive.
• If the serverName cannot be resolved, the operating system's hostname command is used in its place [source].
• If the host header is left out, the server will behave as if usecanonical was on [source].
• Lastly, I just tried exploiting this on my local server, and was unable to spoof the hosts header. I'm not sure if there was an update to Apache that addressed this, or if I was just doing something wrong. Regardless, this header would still be exploitable in environments where virtual hosts are not being used.

Little Rant:

     This question received hundreds of thousands of views without a single mention of the security problems at hand! It shouldn't be this way, but just because a Stack Overflow answer is popular, that doesn't mean it is secure.

Chr(Number) should work for you.

select 'Hello' || chr(10) ||' world' from dual

Remember different platforms expect different new line characters:

• CHR(10) => LF, line feed (unix)
• CHR(13) => CR, carriage return (windows, together with LF)

The other answers all point out that you should not catch generic exceptions, but no one seems to want to tell you why, which is essential to understanding when you can break the "rule". Here is an explanation. Basically, it's so that you don't hide:

• the fact that an error occurred
• the specifics of the error that occurred (error hiding antipattern)

So as long as you take care to do none of those things, it's OK to catch the generic exception. For instance, you could provide information about the exception to the user another way, like:

• Present exceptions as dialogs in a GUI
• Transfer exceptions from a worker thread or process to the controlling thread or process in a multithreading or multiprocessing application

So how to catch the generic exception? There are several ways. If you just want the exception object, do it like this:

try:
    someFunction()
except Exception as ex:
    template = "An exception of type {0} occurred. Arguments:\n{1!r}"
    message = template.format(type(ex).__name__, ex.args)
    print message

Make sure message is brought to the attention of the user in a hard-to-miss way! Printing it, as shown above, may not be enough if the message is buried in lots of other messages. Failing to get the users attention is tantamount to swallowing all exceptions, and if there's one impression you should have come away with after reading the answers on this page, it's that this is not a good thing. Ending the except block with a raise statement will remedy the problem by transparently reraising the exception that was caught.

The difference between the above and using just except: without any argument is twofold:

• A bare except: doesn't give you the exception object to inspect
• The exceptions SystemExit, KeyboardInterrupt and GeneratorExit aren't caught by the above code, which is generally what you want. See the exception hierarchy.

If you also want the same stacktrace you get if you do not catch the exception, you can get that like this (still inside the except clause):

import traceback
print traceback.format_exc()

If you use the logging module, you can print the exception to the log (along with a message) like this:

import logging
log = logging.getLogger()
log.exception("Message for you, sir!")

If you want to dig deeper and examine the stack, look at variables etc., use the post_mortem function of the pdb module inside the except block:

import pdb
pdb.post_mortem()

I've found this last method to be invaluable when hunting down bugs.

It is SUBSTITUTE(B1," ",""), not REPLACE(xx;xx;xx).

I had to use required="required" along with the same name and type, and then validation worked fine.

<input type="radio" name="user-radio"  id="" value="User" required="required" />

<input type="radio" name="user-radio" id="" value="Admin" />

<input type="radio" name="user-radio" id="" value="Guest" /> 

The best way to use constructor

Set s= new HashSet(list);

In java 8 you can also use stream api::

Set s= list.stream().collect(Collectors.toSet());

Using the Date object's methods will could come in handy.

e.g.:

myDate = new Date();
plusSeven = new Date(myDate.setDate(myDate.getDate() + 7));

An alternative to theme_classic() is the theme that comes with the cowplot package, theme_cowplot() (loaded automatically with the package). It looks similar to theme_classic(), with a few subtle differences. Most importantly, the default label sizes are larger, so the resulting figures can be used in publications without further modifications needed (in particular if you save them with save_plot() instead of ggsave()). Also, the background is transparent, not white, which may be useful if you want to edit the figure in illustrator. Finally, faceted plots look better, in my opinion.

Example:

library(cowplot)
a <- seq(1,20)
b <- a^0.25
df <- as.data.frame(cbind(a,b))

p <- ggplot(df, aes(x = a, y = b)) + geom_point()
save_plot('plot.png', p) # alternative to ggsave, with default settings that work well with the theme

This is what the file plot.png produced by this code looks like:

As alternative, php has a built-in timer controller: new EvTimer().

It can be used to make a task scheduler, with proper handling of special cases.

This is not only the Time, but a time transport layer, a chronometer, a lap counter, just as a stopwatch but with php callbacks ;)

EvTimer watchers are simple relative timers that generate an event after a given time, and optionally repeating in regular intervals after that.

The timers are based on real time, that is, if one registers an event that times out after an hour and resets the system clock to January last year, it will still time out after(roughly) one hour.

The callback is guaranteed to be invoked only after its timeout has passed (...). If multiple timers become ready during the same loop iteration then the ones with earlier time-out values are invoked before ones of the same priority with later time-out values.

The timer itself will do a best-effort at avoiding drift, that is, if a timer is configured to trigger every 10 seconds, then it will normally trigger at exactly 10 second intervals. If, however, the script cannot keep up with the timer because it takes longer than those 10 seconds to do) the timer will not fire more than once per event loop iteration.

The first two parameters allows to controls the time delay before execution, and the number of iterations.

The third parameter is a callback function, called at each iteration.

after

    Configures the timer to trigger after after seconds.

repeat

    If repeat is 0.0 , then it will automatically be stopped once the timeout is reached.
    If it is positive, then the timer will automatically be configured to trigger again every repeat seconds later, until stopped manually.

https://www.php.net/manual/en/class.evtimer.php

https://www.php.net/manual/en/evtimer.construct.php

$w2 = new EvTimer(2, 1, function ($w) {
    echo "is called every second, is launched after 2 seconds\n";
    echo "iteration = ", Ev::iteration(), PHP_EOL;

    // Stop the watcher after 5 iterations
    Ev::iteration() == 5 and $w->stop();
    // Stop the watcher if further calls cause more than 10 iterations
    Ev::iteration() >= 10 and $w->stop();
});

We can of course easily create this with basic looping and some tempo with sleep(), usleep(), or hrtime(), but new EvTimer() allows cleans and organized multiples calls, while handling special cases like overlapping.

Like this:

#!/bin/bash

a=2462620
b=2462620

if [ "$a" -eq "$b" ]; then
  echo "They're equal";
fi

Integers can be compared with these operators:

-eq # equal
-ne # not equal
-lt # less than
-le # less than or equal
-gt # greater than
-ge # greater than or equal

It looks like body-parser did support uploading files in Express 3, but support was dropped for Express 4 when it no longer included Connect as a dependency

After looking through some of the modules in mscdex's answer, I found that express-busboy was a far better alternative and the closest thing to a drop-in replacement. The only differences I noticed were in the properties of the uploaded file.

console.log(req.files) using body-parser (Express 3) output an object that looked like this:

{ file: 
   { fieldName: 'file',
     originalFilename: '360px-Cute_Monkey_cropped.jpg',
     name: '360px-Cute_Monkey_cropped.jpg'
     path: 'uploads/6323-16v7rc.jpg',
     type: 'image/jpeg',
     headers: 
      { 'content-disposition': 'form-data; name="file"; filename="360px-Cute_Monkey_cropped.jpg"',
        'content-type': 'image/jpeg' },
     ws: 
      WriteStream { /* ... */ },
     size: 48614 } }

compared to console.log(req.files) using express-busboy (Express 4):

{ file: 
   { field: 'file',
     filename: '360px-Cute_Monkey_cropped.jpg',
     file: 'uploads/9749a8b6-f9cc-40a9-86f1-337a46e16e44/file/360px-Cute_Monkey_cropped.jpg',
     mimetype: 'image/jpeg',
     encoding: '7bit',
     truncated: false
     uuid: '9749a8b6-f9cc-40a9-86f1-337a46e16e44' } }

Using awk

echo $STRING | awk -v N=$N '{print $N}'

Test

% N=3
% STRING="one two three four"
% echo $STRING | awk -v N=$N '{print $N}'

I can see that you want to write you own short javascript for this, but have you considered to use Frameworks for HTML manipulation instead? jQuery is my prefered tool for such a task, eventhough its an overkill for your current question as it has SO many extra functionalities.

Have a look at jQuery here

In an Object Oriented parking lot, there will be no need for attendants because the cars will "know how to park".

Finding a usable car on the lot will be difficult; the most common models will either have all their moving parts exposed as public member variables, or they will be "fully encapsulated" cars with no windows or doors.

The parking spaces in our OO parking lot will not match the size and shape of the cars (an "impediance mismatch" between the spaces and the cars)

License tags on our lot will have a dot between each letter and digit. Handicaped parking will only be available for licenses beginning with "_", and licenses beginning with "m_" will be towed.

Convert.ToDecimal(the double you are trying to convert);

First make sure you are on an instance terminal and you have all access of S3 in IAM you are using. For example I used an ec2 instance.

pip3 install awscli

Then Configure aws

aws configure

Then fill outcredantials ex:-

$ aws configure
AWS Access Key ID [None]: AKIAIOSFODNN7EXAMPLE
AWS Secret Access Key [None]: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
Default region name [None]: us-west-2
Default output format [None]: json (or just press enter)

Now, See all buckets

aws s3 ls

Store all buckets name

aws s3 ls > output.txt

See all file structure in a bucket

aws s3 ls bucket-name --recursive

Store file structure in each bucket

aws s3 ls bucket-name --recursive > file_Structure.txt

Hope this helps.

A possibility is to create a trigger on insert to add in the correct sequence number.

Try closing Android Studio/Eclipse if it's open. It worked for me.

There is also strptime() which expects exactly one format:

$a = strptime('22-09-2008', '%d-%m-%Y');
$timestamp = mktime(0, 0, 0, $a['tm_mon']+1, $a['tm_mday'], $a['tm_year']+1900);

I had the same problem, and solved it as follows:

Actually I want to show Message and close it automatically after 2 second. For that I had to generate (dynamically) simple form and one label showing message, stop message for 1500 ms so user read it. And Close dynamically created form. Shown event occur After load event. So code is

Form MessageForm = new Form();
MessageForm.Shown += (s, e1) => { 
    Thread t = new Thread(() => Thread.Sleep(1500)); 
    t.Start(); 
    t.Join(); 
    MessageForm.Close(); 
};

If the request could not be correctly parsed (including the request entity/body) the appropriate response is 400 Bad Request [1].

RFC 4918 states that 422 Unprocessable Entity is applicable when the request entity is syntactically well-formed, but semantically erroneous. So if the request entity is garbled (like a bad email format) use 400; but if it just doesn't make sense (like @example.com) use 422.

If the issue is that, as stated in the question, user name/email already exists, you could use 409 Conflict [2] with a description of the conflict, and a hint about how to fix it (in this case, "pick a different user name/email"). However in the spec as written, 403 Forbidden [3] can also be used in this case, arguments about HTTP Authorization notwithstanding.

412 Precondition Failed [4] is used when a precondition request header (e.g. If-Match) that was supplied by the client evaluates to false. That is, the client requested something and supplied preconditions, knowing full well that those preconditions might fail. 412 should never be sprung on the client out of the blue, and shouldn't be related to the request entity per se.

Use Method to Serialize and Deserialize Collection object from memory. This works on Collection Data Types. This Method will Serialize collection of any type to a byte stream. Create a Seperate Class SerilizeDeserialize and add following two methods:

public class SerilizeDeserialize
{

    // Serialize collection of any type to a byte stream

    public static byte[] Serialize<T>(T obj)
    {
        using (MemoryStream memStream = new MemoryStream())
        {
            BinaryFormatter binSerializer = new BinaryFormatter();
            binSerializer.Serialize(memStream, obj);
            return memStream.ToArray();
        }
    }

    // DSerialize collection of any type to a byte stream

    public static T Deserialize<T>(byte[] serializedObj)
    {
        T obj = default(T);
        using (MemoryStream memStream = new MemoryStream(serializedObj))
        {
            BinaryFormatter binSerializer = new BinaryFormatter();
            obj = (T)binSerializer.Deserialize(memStream);
        }
        return obj;
    }

}

How To use these method in your Class:

ArrayList arrayListMem = new ArrayList() { "One", "Two", "Three", "Four", "Five", "Six", "Seven" };
Console.WriteLine("Serializing to Memory : arrayListMem");
byte[] stream = SerilizeDeserialize.Serialize(arrayListMem);

ArrayList arrayListMemDes = new ArrayList();

arrayListMemDes = SerilizeDeserialize.Deserialize<ArrayList>(stream);

Console.WriteLine("DSerializing From Memory : arrayListMemDes");
foreach (var item in arrayListMemDes)
{
    Console.WriteLine(item);
}

Replace your recyclerView with,

<android.support.v7.widget.RecyclerView
    android:id="@+id/conversation"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

here,

app:layout_behavior="@string/appbar_scrolling_view_behavior"

will manage the rest of things.

One more thing, no need to put your recyclerView inside NestedScrollView

Double underscore. That mangles the name. The variable can still be accessed, but it's generally a bad idea to do so.

Use single underscores for semi-private (tells python developers "only change this if you absolutely must") and doubles for fully private.

Use typedefs to define more complicated types i.e function pointers

I will take the example of defining a state-machine in C

    typedef  int (*action_handler_t)(void *ctx, void *data);

now we have defined a type called action_handler that takes two pointers and returns a int

define your state-machine

    typedef struct
    {
      state_t curr_state;   /* Enum for the Current state */
      event_t event;  /* Enum for the event */
      state_t next_state;   /* Enum for the next state */
      action_handler_t event_handler; /* Function-pointer to the action */

     }state_element;

The function pointer to the action looks like a simple type and typedef primarily serves this purpose.

All my event handlers now should adhere to the type defined by action_handler

    int handle_event_a(void *fsm_ctx, void *in_msg );

    int handle_event_b(void *fsm_ctx, void *in_msg );

I had the same issue and it turns out there was an error in the directory of the file I was trying to serve instead of:

app.use(express.static(__dirname + '/../dist'));

I had :

app.use(express.static('./dist'));

Instead of getting IMEI from TelephonyManager use ANDROID_ID.

This works for each android device irrespective of having telephony.

<context:component-scan base-package="" /> 

tells Spring to scan those packages for Annotations.

<mvc:annotation-driven> 

registers a RequestMappingHanderMapping, a RequestMappingHandlerAdapter, and an ExceptionHandlerExceptionResolver to support the annotated controller methods like @RequestMapping, @ExceptionHandler, etc. that come with MVC.

This also enables a ConversionService that supports Annotation driven formatting of outputs as well as Annotation driven validation for inputs. It also enables support for @ResponseBody which you can use to return JSON data.

You can accomplish the same things using Java-based Configuration using @ComponentScan(basePackages={"...", "..."} and @EnableWebMvc in a @Configuration class.

try

console.log($("#"+d));

your solution is passing the double quotes as part of the string.

You can't create a method swap, so that after calling swap(x,y) the values of x and y will be swapped. You could create such a method for mutable classes by swapping their contents¹, but this would not change their object identity and you could not define a general method for this.

You can however write a method that swaps two items in an array or list if that's what you want.

¹ For example you could create a swap method that takes two lists and after executing the method, list x will have the previous contents of list y and list y will have the previous contents of list x.

No. The first returns a DOM element, or null, whereas the second always returns a jQuery object. The jQuery object will be empty if no element with the id of contents was matched.

The DOM element returned by document.getElementById('contents') allows you to do things such as change the .innerHTML (or .value) etc, however you'll need to use jQuery methods on the jQuery Object.

var contents = $('#contents').get(0);

Is more equivilent, however if no element with the id of contents is matched, document.getElementById('contents') will return null, but $('#contents').get(0) will return undefined.

One benefit on using the jQuery object is that you won't get any errors if no elements were returned, as an object is always returned. However you will get errors if you try to perform operations on the null returned by document.getElementById

With New-Item you can add the Force parameter

New-Item -Force -ItemType directory -Path foo

Or the ErrorAction parameter

New-Item -ErrorAction Ignore -ItemType directory -Path foo

We use {SmartAssembly} for .NET protection of an enterprise level distributed application, and it has worked great for us.

Okay, so I figured out what the problem was, and the approach I believe works best. In my case, because the two objects weren't identical from a Javascript perspective, as in: they may have shared the same values, but they were different actual objects, e.g. originalObject was instantiated entirely separately from objects which was essentially an array of reference data (to populate the dropdown).

I found that the approach that worked best for me was to compare a unique property of the objects, rather than directly compare the two entire objects. This comparison is done in the bound property selected:

<select [ngModel]="originalObject">
    <option *ngFor="let object of objects" [ngValue]="object" [selected]="object.uniqueId === originalObject.uniqueId">{{object.name}}</option>
</select>

I ended here, because I googled for "python first and last element of array", and found everything else but this. So here's the answer to the title question:

a = [1,2,3]
a[0] # first element (returns 1)
a[-1] # last element (returns 3)

You can use the Google Docs PDF-viewing widget, if you don't mind having them host the "application" itself.

I had more suggestions, but stack overflow only lets me post one hyperlink as a new user, sorry.

in the terminal on your mac os or linux os type this code

mail -s (subject) (receiversEmailAddress)  <<< "how are you?"

for an example try this

mail -s "hi" [email protected] <<< "how are you?"<br>

I tried Omega's example however it was not working with my C# code. I recommend using this instead:

[RegularExpression(@"^(?=[^\d_].*?\d)\w(\w|[!@#$%]){7,20}", ErrorMessage = @"Error. Password must have one capital, one special character and one numerical character. It can not start with a special character or a digit.")]

My crystal ball says that you are loading the model using either file:// or C:/, which stays true to the error message as they are not http://

So you can either install a webserver in your local PC or upload the model somewhere else and use jsonp and change the url to http://example.com/path/to/model

Origin is defined in RFC-6454 as

   ...they have the same
   scheme, host, and port.  (See Section 4 for full details.)

So even though your file originates from the same host (localhost), but as long as the scheme is different (http / file), they are treated as different origin.

The ActivityResultRegistry is the recommended approach

ComponentActivity now provides an ActivityResultRegistry that lets you handle the startActivityForResult()+onActivityResult() as well as requestPermissions()+onRequestPermissionsResult() flows without overriding methods in your Activity or Fragment, brings increased type safety via ActivityResultContract, and provides hooks for testing these flows.

It is strongly recommended to use the Activity Result APIs introduced in AndroidX Activity 1.2.0-alpha02 and Fragment 1.3.0-alpha02.

Add this to your build.gradle

def activity_version = "1.2.0-beta01"

// Java language implementation
implementation "androidx.activity:activity:$activity_version"
// Kotlin
implementation "androidx.activity:activity-ktx:$activity_version"

How to use the pre-built contract?

This new API has the following pre built functionalities

1. TakeVideo
2. PickContact
3. GetContent
4. GetContents
5. OpenDocument
6. OpenDocuments
7. OpenDocumentTree
8. CreateDocument
9. Dial
10. TakePicture
11. RequestPermission
12. RequestPermissions

An example that uses takePicture contract:

private val takePicture = prepareCall(ActivityResultContracts.TakePicture()) { bitmap: Bitmap? ->
    // Do something with the Bitmap, if present
}
    
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)
    
    button.setOnClickListener { takePicture() }
}

So what’s going on here? Let’s break it down slightly. takePicture is just a callback which returns a nullable Bitmap - whether or not it’s null depends on whether or not the onActivityResult process was successful. prepareCall then registers this call into a new feature on ComponentActivity called the ActivityResultRegistry - we’ll come back to this later. ActivityResultContracts.TakePicture() is one of the built-in helpers which Google have created for us, and finally invoking takePicture actually triggers the Intent in the same way that you would previously with Activity.startActivityForResult(intent, REQUEST_CODE).

How to write a custom contract?

Simple contract that takes an Int as an Input and returns a String that requested Activity returns in the result Intent.

class MyContract : ActivityResultContract<Int, String>() {

    companion object {
        const val ACTION = "com.myapp.action.MY_ACTION"
        const val INPUT_INT = "input_int"
        const val OUTPUT_STRING = "output_string"
    }

    override fun createIntent(input: Int): Intent {
        return Intent(ACTION)
            .apply { putExtra(INPUT_INT, input) }
    }

    override fun parseResult(resultCode: Int, intent: Intent?): String? {
        return when (resultCode) {
            Activity.RESULT_OK -> intent?.getStringExtra(OUTPUT_STRING)
            else -> null
        }
    }
}

class MyActivity : AppCompatActivity() {

    private val myActionCall = prepareCall(MyContract()) { result ->
        Log.i("MyActivity", "Obtained result: $result")
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        ...
        button.setOnClickListener {
            myActionCall(500)
        }
    }
}

If you want to avoid using an extra Class and List<Object> genomes you could simply use a Map.

The data structure translates into Map<String, List<Country>>

String resourceEndpoint = "http://api.geonames.org/countryInfoJSON?username=volodiaL";

Map<String, List<Country>> geonames = restTemplate.getForObject(resourceEndpoint, Map.class);

List<Country> countries = geonames.get("geonames");

In general, one doesn't expand out log(a + b); you just deal with it as is. That said, there are occasionally circumstances where it makes sense to use the following identity:

log(a + b) = log(a * (1 + b/a)) = log a + log(1 + b/a)

(In fact, this identity is often used when implementing log in math libraries).

Ideally, you would create a method on the choice object that found itself in votes, or create a relationship between the models. A template tag that performed the dictionary lookup would work, too.

If you want to know the port number of your local host on which Mysql is running you can use this query on MySQL Command line client --

SHOW VARIABLES WHERE Variable_name = 'port';


mysql> SHOW VARIABLES WHERE Variable_name = 'port';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| port          | 3306  |
+---------------+-------+
1 row in set (0.00 sec)

It will give you the port number on which MySQL is running.

If you want to know the hostname of your Mysql you can use this query on MySQL Command line client --

SHOW VARIABLES WHERE Variable_name = 'hostname';


mysql> SHOW VARIABLES WHERE Variable_name = 'hostname';
+-------------------+-------+
| Variable_name     | Value |
+-------------------+-------+
| hostname          | Dell  |
+-------------------+-------+
1 row in set (0.00 sec)

It will give you the hostname for mysql.

If you want to know the username of your Mysql you can use this query on MySQL Command line client --

select user();   


mysql> select user();
+----------------+
| user()         |
+----------------+
| root@localhost |
+----------------+
1 row in set (0.00 sec)

It will give you the username for mysql.

You can try icomet(https://github.com/ideawu/icomet), a C1000K C++ comet server built with libevent. icomet also provides a JavaScript library, it is easy to use as simple as

var comet = new iComet({
    sign_url: 'http://' + app_host + '/sign?obj=' + obj,
    sub_url: 'http://' + icomet_host + '/sub',
    callback: function(msg){
        // on server push
        alert(msg.content);
    }
});

icomet supports a wide range of Browsers and OSes, including Safari(iOS, Mac), IEs(Windows), Firefox, Chrome, etc.

Here's a one line solution without a while loop.

The order is preserved in the resulting list.

The potential downsides are

1. It clones the regex for every match.
2. The result is in a different form than expected solutions. You'll need to process them one more time.

let re = /\s*([^[:]+):\"([^"]+)"/g
let str = '[description:"aoeu" uuid:"123sth"]'

(str.match(re) || []).map(e => RegExp(re.source, re.flags).exec(e))

[ [ 'description:"aoeu"',
    'description',
    'aoeu',
    index: 0,
    input: 'description:"aoeu"',
    groups: undefined ],
  [ ' uuid:"123sth"',
    'uuid',
    '123sth',
    index: 0,
    input: ' uuid:"123sth"',
    groups: undefined ] ]

A possible solution might be to use the JSON dumps() method, so you can convert the dictionary to a string ---

import json

a={"a":10, "b":20}
b={"b":20, "a":10}
c = [json.dumps(a), json.dumps(b)]


set(c)
json.dumps(a) in c

Output -

set(['{"a": 10, "b": 20}'])
True

there are several ways. You can use this method:

start = @selected_date.beginning_of_day
end = @selected_date.end_of_day
@comments = Comment.where("DATE(created_at) BETWEEN ? AND ?", start, end)

Or this:

@comments = Comment.where(:created_at => @selected_date.beginning_of_day..@selected_date.end_of_day)

From EL 2.2 specification (get the one below "Click here to download the spec for evaluation"):

1.10 Empty Operator - empty A

The empty operator is a prefix operator that can be used to determine if a value is null or empty.

To evaluate empty A

• If A is null, return true
• Otherwise, if A is the empty string, then return true
• Otherwise, if A is an empty array, then return true
• Otherwise, if A is an empty Map, return true
• Otherwise, if A is an empty Collection, return true
• Otherwise return false

So, considering the interfaces, it works on Collection and Map only. In your case, I think Collection is the best option. Or, if it's a Javabean-like object, then Map. Either way, under the covers, the isEmpty() method is used for the actual check. On interface methods which you can't or don't want to implement, you could throw UnsupportedOperationException.

The main difference between the web containers and application server is that most web containers such as Apache Tomcat implements only basic JSR like Servlet, JSP, JSTL wheres Application servers implements the entire Java EE Specification. Every application server contains web container.

Assuming you already have a JFrame to call this from:

JOptionPane.showMessageDialog(frame, "thank you for using java");

Here is another one if anyone needs one for minutes and seconds:

    var mins = 10;  //Set the number of minutes you need
    var secs = mins * 60;
    var currentSeconds = 0;
    var currentMinutes = 0;
    /* 
     * The following line has been commented out due to a suggestion left in the comments. The line below it has not been tested. 
     * setTimeout('Decrement()',1000);
     */
    setTimeout(Decrement,1000); 

    function Decrement() {
        currentMinutes = Math.floor(secs / 60);
        currentSeconds = secs % 60;
        if(currentSeconds <= 9) currentSeconds = "0" + currentSeconds;
        secs--;
        document.getElementById("timerText").innerHTML = currentMinutes + ":" + currentSeconds; //Set the element id you need the time put into.
        if(secs !== -1) setTimeout('Decrement()',1000);
    }

Here's a good one:

Set line-height equal to whatever the height is; works like a charm!

E.g:

li {
    height: 30px;
    line-height: 30px;
}

I found that this works really well in Chrome.

Right click on the element that you'd like to inspect, then click Force Element State > Hover. Screenshot attached.

Most of the time it happens because of the wrong key (AWS_SECRET_ACCESS_KEY). Please cross verify your AWS_SECRET_ACCESS_KEY. Hope it will work...

Yes it's pretty work with jquery.serialize()

HTML

<form id="myform" class="myform" method="post" name="myform">
<textarea id="myField" type="text" name="myField"></textarea>
<input type="checkbox" name="myCheckboxes[]" id="myCheckboxes" value="someValue1" />
<input type="checkbox" name="myCheckboxes[]" id="myCheckboxes" value="someValue2" />
<input id="submit" type="submit" name="submit" value="Submit" onclick="return submitForm()" />
</form>
 <div id="myResponse"></div>

JQuery

function submitForm() {
var form = document.myform;

var dataString = $(form).serialize();


$.ajax({
    type:'POST',
    url:'myurl.php',
    data: dataString,
    success: function(data){
        $('#myResponse').html(data);


    }
});
return false;
}

NOW THE PHP, i export the POST data

 echo var_export($_POST);

You can see the all the checkbox value are sent.I hope it may help you

The error seems clear: model objects do not support item assignment. MyModel.objects.latest('id')['foo'] = 'bar' will throw this same error.

It's a little confusing that your model instance is called projectForm...

To reproduce your first block of code in a loop, you need to use setattr

for k,v in session_results.iteritems():
    setattr(projectForm, k, v)

This is a few months late but I thought I'd provide my solution based on this here tutorial. The gist of it is that it's a lot easier to manage once you change the way you approach forms.

First, use ReactiveFormsModule instead of or in addition to the normal FormsModule. With reactive forms you create your forms in your components/services and then plug them into your page instead of your page generating the form itself. It's a bit more code but it's a lot more testable, a lot more flexible, and as far as I can tell the best way to make a lot of non-trivial forms.

The end result will look a little like this, conceptually:

• You have one base FormGroup with whatever FormControl instances you need for the entirety of the form. For example, as in the tutorial I linked to, lets say you want a form where a user can input their name once and then any number of addresses. All of the one-time field inputs would be in this base form group.

• Inside that FormGroup instance there will be one or more FormArray instances. A FormArray is basically a way to group multiple controls together and iterate over them. You can also put multiple FormGroup instances in your array and use those as essentially "mini-forms" nested within your larger form.

• By nesting multiple FormGroup and/or FormControl instances within a dynamic FormArray, you can control validity and manage the form as one, big, reactive piece made up of several dynamic parts. For example, if you want to check if every single input is valid before allowing the user to submit, the validity of one sub-form will "bubble up" to the top-level form and the entire form becomes invalid, making it easy to manage dynamic inputs.

• As a FormArray is, essentially, a wrapper around an array interface but for form pieces, you can push, pop, insert, and remove controls at any time without recreating the form or doing complex interactions.

In case the tutorial I linked to goes down, here some sample code you can implement yourself (my examples use TypeScript) that illustrate the basic ideas:

Base Component code:

import { Component, Input, OnInit } from '@angular/core';
import { FormArray, FormBuilder, FormGroup, Validators } from '@angular/forms';

@Component({
  selector: 'my-form-component',
  templateUrl: './my-form.component.html'
})
export class MyFormComponent implements OnInit {
    @Input() inputArray: ArrayType[];
    myForm: FormGroup;

    constructor(private fb: FormBuilder) {}
    ngOnInit(): void {
        let newForm = this.fb.group({
            appearsOnce: ['InitialValue', [Validators.required, Validators.maxLength(25)]],
            formArray: this.fb.array([])
        });

        const arrayControl = <FormArray>newForm.controls['formArray'];
        this.inputArray.forEach(item => {
            let newGroup = this.fb.group({
                itemPropertyOne: ['InitialValue', [Validators.required]],
                itemPropertyTwo: ['InitialValue', [Validators.minLength(5), Validators.maxLength(20)]]
            });
            arrayControl.push(newGroup);
        });

        this.myForm = newForm;
    }
    addInput(): void {
        const arrayControl = <FormArray>this.myForm.controls['formArray'];
        let newGroup = this.fb.group({

            /* Fill this in identically to the one in ngOnInit */

        });
        arrayControl.push(newGroup);
    }
    delInput(index: number): void {
        const arrayControl = <FormArray>this.myForm.controls['formArray'];
        arrayControl.removeAt(index);
    }
    onSubmit(): void {
        console.log(this.myForm.value);
        // Your form value is outputted as a JavaScript object.
        // Parse it as JSON or take the values necessary to use as you like
    }
}

Sub-Component Code: (one for each new input field, to keep things clean)

import { Component, Input } from '@angular/core';
import { FormGroup } from '@angular/forms';

@Component({
    selector: 'my-form-sub-component',
    templateUrl: './my-form-sub-component.html'
})
export class MyFormSubComponent {
    @Input() myForm: FormGroup; // This component is passed a FormGroup from the base component template
}

Base Component HTML

<form [formGroup]="myForm" (ngSubmit)="onSubmit()" novalidate>
    <label>Appears Once:</label>
    <input type="text" formControlName="appearsOnce" />

    <div formArrayName="formArray">
        <div *ngFor="let control of myForm.controls['formArray'].controls; let i = index">
            <button type="button" (click)="delInput(i)">Delete</button>
            <my-form-sub-component [myForm]="myForm.controls.formArray.controls[i]"></my-form-sub-component>
        </div>
    </div>
    <button type="button" (click)="addInput()">Add</button>
    <button type="submit" [disabled]="!myForm.valid">Save</button>
</form>

Sub-Component HTML

<div [formGroup]="form">
    <label>Property One: </label>
    <input type="text" formControlName="propertyOne"/>

    <label >Property Two: </label>
    <input type="number" formControlName="propertyTwo"/>
</div>

In the above code I basically have a component that represents the base of the form and then each sub-component manages its own FormGroup instance within the FormArray situated inside the base FormGroup. The base template passes along the sub-group to the sub-component and then you can handle validation for the entire form dynamically.

Also, this makes it trivial to re-order component by strategically inserting and removing them from the form. It works with (seemingly) any number of inputs as they don't conflict with names (a big downside of template-driven forms as far as I'm aware) and you still retain pretty much automatic validation. The only "downside" of this approach is, besides writing a little more code, you do have to relearn how forms work. However, this will open up possibilities for much larger and more dynamic forms as you go on.

If you have any questions or want to point out some errors, go ahead. I just typed up the above code based on something I did myself this past week with the names changed and other misc. properties left out, but it should be straightforward. The only major difference between the above code and my own is that I moved all of the form-building to a separate service that's called from the component so it's a bit less messy.

Detect OS Version:

    public static string OS_Name()
    {
        return (string)(from x in new ManagementObjectSearcher(
            "SELECT Caption FROM Win32_OperatingSystem").Get().Cast<ManagementObject>() 
            select x.GetPropertyValue("Caption")).FirstOrDefault();
    }

The following example creates a SqlConnection and a SqlTransaction. It also demonstrates how to use the BeginTransaction, Commit, and Rollback methods. The transaction is rolled back on any error, or if it is disposed without first being committed. Try/Catch error handling is used to handle any errors when attempting to commit or roll back the transaction.

private static void ExecuteSqlTransaction(string connectionString)
{
    using (SqlConnection connection = new SqlConnection(connectionString))
    {
        connection.Open();

        SqlCommand command = connection.CreateCommand();
        SqlTransaction transaction;

        // Start a local transaction.
        transaction = connection.BeginTransaction("SampleTransaction");

        // Must assign both transaction object and connection 
        // to Command object for a pending local transaction
        command.Connection = connection;
        command.Transaction = transaction;

        try
        {
            command.CommandText =
                "Insert into Region (RegionID, RegionDescription) VALUES (100, 'Description')";
            command.ExecuteNonQuery();
            command.CommandText =
                "Insert into Region (RegionID, RegionDescription) VALUES (101, 'Description')";
            command.ExecuteNonQuery();

            // Attempt to commit the transaction.
            transaction.Commit();
            Console.WriteLine("Both records are written to database.");
        }
        catch (Exception ex)
        {
            Console.WriteLine("Commit Exception Type: {0}", ex.GetType());
            Console.WriteLine("  Message: {0}", ex.Message);

            // Attempt to roll back the transaction. 
            try
            {
                transaction.Rollback();
            }
            catch (Exception ex2)
            {
                // This catch block will handle any errors that may have occurred 
                // on the server that would cause the rollback to fail, such as 
                // a closed connection.
                Console.WriteLine("Rollback Exception Type: {0}", ex2.GetType());
                Console.WriteLine("  Message: {0}", ex2.Message);
            }
        }
    }
}

This problem has very simple solution. Just open your SmartGit, then go to Repository option(On top left), then go to settings. It will open a dialog box of Repository Settings. Now, click on Commit TAB and write your UserName and EmailId which you give on BitBucke website. Now click ok and again try to Commit and it works fine now.

Since pip is a package, pip uninstall pip Will do it.

Try HashSet:

The HashSet(Of T) class provides high-performance set operations. A set is a collection that contains no duplicate elements, and whose elements are in no particular order...

The capacity of a HashSet(Of T) object is the number of elements that the object can hold. A HashSet(Of T) object's capacity automatically increases as elements are added to the object.

The HashSet(Of T) class is based on the model of mathematical sets and provides high-performance set operations similar to accessing the keys of the Dictionary(Of TKey, TValue) or Hashtable collections. In simple terms, the HashSet(Of T) class can be thought of as a Dictionary(Of TKey, TValue) collection without values.

A HashSet(Of T) collection is not sorted and cannot contain duplicate elements...

int is a primitive datatype whereas Integer is an object. Creating an object with Integer will give you access to all the methods that are available in the Integer class. But, if you create a primitive data type with int, you will not be able to use those inbuild methods and you have to define them by yourself. But, if you don't want any other methods and want to make the program more memory efficient, you can go with primitive datatype because creating an object will increase the memory consumption.

Try this sqlite table schema parser, I implemented the sqlite table parser for parsing the table definitions in PHP.

It returns the full definitions (unique, primary key, type, precision, not null, references, table constraints... etc)

https://github.com/maghead/sqlite-parser

If you want to get single row and from the that row single column, one line code to get the value of the specific column is to use find() method alongside specifying of the column that you want to retrieve it.

Here is sample code:

ModelName::find($id_of_the_record, ['column_name'])->toArray()['column_name'];

with all the adjusting css. if possible, wrap it with a table with height and width as 100% and td set it to vertical align to middle, text-align to center

try this ( stringWithFormat has to start with lowercase)

 [NSString stringWithFormat:@"%@\n%@",string1,string2];

SELECT (sub)queries return result sets. So you need to use IN, not = in your WHERE clause.

Additionally, as shown in this answer you cannot modify the same table from a subquery within the same query. However, you can either SELECT then DELETE in separate queries, or nest another subquery and alias the inner subquery result (looks rather hacky, though):

DELETE FROM posts WHERE id IN (
    SELECT * FROM (
        SELECT id FROM posts GROUP BY id HAVING ( COUNT(id) > 1 )
    ) AS p
)

Or use joins as suggested by Mchl.

PATH: Answered long ago, however, it maybe more helpful to think of -p as "Path" (easier to remember), as in this causes mkdir to create every part of the path that isn't already there.

mkdir -p /usr/bin/comm/diff/er/fence

if /usr/bin/comm already exists, it acts like: mkdir /usr/bin/comm/diff mkdir /usr/bin/comm/diff/er mkdir /usr/bin/comm/diff/er/fence

As you can see, it saves you a bit of typing, and thinking, since you don't have to figure out what's already there and what isn't.

$(window).mouseleave(function(event) {
  if (event.toElement == null) {
    //Do something
  }
})

This might be a bit hacky but it will only trigger when the mouse leaves the window. I kept catching child events and this resolved it

If you have the following:

public class A
{
}

public class B extends A
{
}

then B is a subclass of A, B inherits from A. The opposite would be superclass.

Most replies here need to import numpy as np

There is a built-in solution into pandas itself: pd.NA, to use like this:

df.replace('N/A', pd.NA)

inih is a simple ini parser written in C, it comes with a C++ wrapper too. Example usage:

#include "INIReader.h"    

INIReader reader("test.ini");

std::cout << "version="
          << reader.GetInteger("protocol", "version", -1) << ", name="
          << reader.Get("user", "name", "UNKNOWN") << ", active="
          << reader.GetBoolean("user", "active", true) << "\n";

Using TimeZones class makes it easy to create timezone specific date.

TimeZoneInfo.ConvertTime(DateTime.Now, TimeZoneInfo.FindSystemTimeZoneById(TimeZones.Paris.Id));

You can't replace ? in your query with an arbitrary number of values. Each ? is a placeholder for a single value only. To support an arbitrary number of values, you'll have to dynamically build a string containing ?, ?, ?, ... , ? with the number of question marks being the same as the number of values you want in your in clause.

List1 = [[10,-13,17],[3,5,1],[13,11,12]]

num = 50
for i in List1[0]:num -= i
print num

For example you might decide a LinkedList is the best choice for your application, but then later decide ArrayList might be a better choice for performance reason.

Use:

List list = new ArrayList(100); // will be better also to set the initial capacity of a collection 

Instead of:

ArrayList list = new ArrayList();

For reference:

Please try this code:

$("#YourSelect>option:selected").html()

I think, below snippet can be used to list all the files.

#include <stdio.h>
#include <dirent.h>
#include <sys/types.h>

int main(int argc, char** argv) { 
    list_dir("myFolderName");
    return EXIT_SUCCESS;
}  

static void list_dir(const char *path) {
    struct dirent *entry;
    DIR *dir = opendir(path);
    if (dir == NULL) {
        return;
    }

    while ((entry = readdir(dir)) != NULL) {
        printf("%s\n",entry->d_name);
    }

    closedir(dir);
}

This is the structure used (present in dirent.h):

struct dirent {
    ino_t d_ino; /* inode number */
    off_t d_off; /* offset to the next dirent */
    unsigned short d_reclen; /* length of this record */
    unsigned char d_type; /* type of file */
    char d_name[256]; /* filename */
};

if you like to use for URLRequest httpBody

extension Dictionary {

    func toString() -> String? {
        return (self.compactMap({ (key, value) -> String in
            return "\(key)=\(value)"
        }) as Array).joined(separator: "&")
    }

}

// print: Fields=sdad&ServiceId=1222

A nice way is to use Spring's ResponseStatusException

Rather than returning a ResponseEntityor similar you simply throw the ResponseStatusException from the controller with an HttpStatus and cause, for example:

throw new ResponseStatusException(HttpStatus.BAD_REQUEST, "Cause description here");

or:

throw new ResponseStatusException(HttpStatus.INTERNAL_SERVER_ERROR, "Cause description here");

This results in a response to the client containing the HTTP status (e.g. 400 Bad request) with a body like:

{
  "timestamp": "2020-07-09T04:43:04.695+0000",
  "status": 400,
  "error": "Bad Request",
  "message": "Cause description here",
  "path": "/test-api/v1/search"
}

#include <iostream>
#include <iomanip>
#include <sstream>

int main()
{
    int x, y;
    std::stringstream stream;

    std::cin >> x;
    stream << x;
    stream >> std::hex >> y;
    std::cout << y;

    return 0;
}

Installing the "security" package extras for requests solved for me:

sudo apt-get install libffi-dev
sudo pip install -U requests[security]

a = [5, 1, 6, 14, 2, 8]
b = [2, 6, 15]

a - b
# => [5, 1, 14, 8]

b - a
# => [15]

(b - a).empty?
# => false

I'm not sure of the details as you haven't posted the whole code, but:

• remember to override hashCode() as well
• the equals method should have Object, not People as its argument type. At the moment you are overloading, not overriding, the equals method, which probably isn't what you want, especially given that you check its type later.
• you can use instanceof to check it is a People object e.g. if (!(other instanceof People)) { result = false;}
• equals is used for all objects, but not primitives. I think you mean age is an int (primitive), in which case just use ==. Note that an Integer (with a capital 'I') is an Object which should be compared with equals.

See What issues should be considered when overriding equals and hashCode in Java? for more details.

I found slightly different problem running R on through mac terminal, but connecting remotely to an Ubuntu server, which prevented me from successfully installing a library.

The solution I have was finding out what "LANG" variable is used in Ubuntu terminal

Ubuntu > echo $LANG
en_US.TUF-8

I got "en_US.TUF-8" reply from Ubuntu.

In R session, however, I got "UTF-8" as the default value and it complained that LC_TYPEC Setting LC_CTYPE failed, using "C"

R> Sys.getenv("LANG")
"UTF-8"

So, I tried to change this variable in R. It worked.

R> Sys.setenv(LANG="en_US.UTF-8")

Trigger Click

$("#checkAll").click(function(){
    $('input:checkbox').click();
});

OR

$("#checkAll").click(function(){
    $('input:checkbox').trigger('click');
});

OR

$("#checkAll").click(function(){
    $('input:checkbox').prop('checked', this.checked);
});

In SQL, the order of the output is not defined unless you specify it in the ORDER BY clause.

Try this:

SELECT  *
FROM    one
JOIN    two
ON      one.one_name = two.one_name
ORDER BY
        one.id

Use sort -n or sort --numeric-sort.

I had the same issue and found a solution :

Previous code:

    <EditText 
    android:layout_height="wrap_content"
    android:gravity="center" 
    android:inputType ="password" 
    android:layout_width="fill_parent"
    android:id="@+id/password" 
    android:hint="password" 
    android:maxLines="1">
    </EditText>

Solution:

<EditText 
android:layout_height="wrap_content"
android:gravity="center" 
android:password="true" 
android:layout_width="fill_parent"
android:id="@+id/password" 
android:hint="password" 
android:maxLines="1">
</EditText>

The previous code does not show the 'hint', but when I changed it to the last one it started showing...

hope this be helpful to someone...

If this scales appropriately (i.e. you don't run into memory problems), the full problem would take about 130*0.2 seconds = 26 seconds on a comparable machine (I did this on a 2-year-old MacBook Pro).

Functions are computed values and cannot perform permanent environmental changes to SQL Server (i.e., no INSERT or UPDATE statements allowed).

A function can be used inline in SQL statements if it returns a scalar value or can be joined upon if it returns a result set.

A point worth noting from comments, which summarize the answer. Thanks to @Sean K Anderson:

Functions follow the computer-science definition in that they MUST return a value and cannot alter the data they receive as parameters (the arguments). Functions are not allowed to change anything, must have at least one parameter, and they must return a value. Stored procs do not have to have a parameter, can change database objects, and do not have to return a value.

I think this is the culprit:

cmd = new SqlCommand(query, con);

DataTable dt = Select(query);

cmd.ExecuteNonQuery();

ddtype.DataSource = dt;

I don't know what that code is supposed to do, but it looks like you want to create an SqlDataReader for that, as explained here and all over the web if you search for "SqlCommand DropDownList DataSource":

cmd = new SqlCommand(query, con);
ddtype.DataSource = cmd.ExecuteReader();

Or you can create a DataTable as explained here:

cmd = new SqlCommand(query, con);

SqlDataAdapter listQueryAdapter = new SqlDataAdapter(cmd);
DataTable listTable = new DataTable();
listQueryAdapter.Fill(listTable);

ddtype.DataSource = listTable;

In Chrome, go to options (Customize and Control, the 3 dots/bars at top right) ---> More Tools ---> save page as

save page as  
filename     : any_name.html 
save as type : webpage complete.

Then you will get any_name.html and any_name folder.

The first allocates an object with automatic storage duration, which means it will be destructed automatically upon exit from the scope in which it is defined.

The second allocated an object with dynamic storage duration, which means it will not be destructed until you explicitly use delete to do so.

using(StreamWriter writer = new StreamWriter("debug.txt", true))
{
  writer.WriteLine("whatever you text is");
}

The second "true" parameter tells it to append.

If you are using freezegun package in tests you may need to have more smart isinstance checks which works well with FakeDate and original Date/Datetime beeing inside with freeze_time context:

def isinstance_date(value):
    """Safe replacement for isinstance date which works smoothly also with Mocked freezetime"""
    import datetime
    if isinstance(value, datetime.date) and not isinstance(value, datetime.datetime):
        return True
    elif type(datetime.datetime.today().date()) == type(value):
        return True
    else:
        return False


def isinstance_datetime(value):
    """Safe replacement for isinstance datetime which works smoothly also with Mocked freezetime """
    import datetime
    if isinstance(value, datetime.datetime):
        return True
    elif type(datetime.datetime.now()) == type(value):
        return True
    else:
        return False

and tests to verify the implementation

class TestDateUtils(TestCase):

    def setUp(self):
        self.date_orig = datetime.date(2000, 10, 10)
        self.datetime_orig = datetime.datetime(2000, 10, 10)

        with freeze_time('2001-01-01'):
            self.date_freezed = datetime.date(2002, 10, 10)
            self.datetime_freezed = datetime.datetime(2002, 10, 10)

    def test_isinstance_date(self):
        def check():
            self.assertTrue(isinstance_date(self.date_orig))
            self.assertTrue(isinstance_date(self.date_freezed))
            self.assertFalse(isinstance_date(self.datetime_orig))
            self.assertFalse(isinstance_date(self.datetime_freezed))
            self.assertFalse(isinstance_date(None))

        check()
        with freeze_time('2005-01-01'):
            check()

    def test_isinstance_datetime(self):
        def check():
            self.assertFalse(isinstance_datetime(self.date_orig))
            self.assertFalse(isinstance_datetime(self.date_freezed))
            self.assertTrue(isinstance_datetime(self.datetime_orig))
            self.assertTrue(isinstance_datetime(self.datetime_freezed))

A complete example using schedule and multiprocessing, with on and off control and parameter to run_job() the return codes are simplified and interval is set to 10sec, change to every(2).hour.do()for 2hours. Schedule is quite impressive it does not drift and I've never seen it more than 100ms off when scheduling. Using multiprocessing instead of threading because it has a termination method.

#!/usr/bin/env python3

import schedule
import time
import datetime
import uuid

from flask import Flask, request
from multiprocessing import Process

app = Flask(__name__)
t = None
job_timer = None

def run_job(id):
    """ sample job with parameter """
    global job_timer
    print("timer job id={}".format(id))
    print("timer: {:.4f}sec".format(time.time() - job_timer))
    job_timer = time.time()

def run_schedule():
    """ infinite loop for schedule """
    global job_timer
    job_timer = time.time()
    while 1:
        schedule.run_pending()
        time.sleep(1)

@app.route('/timer/<string:status>')
def mytimer(status, nsec=10):
    global t, job_timer
    if status=='on' and not t:
        schedule.every(nsec).seconds.do(run_job, str(uuid.uuid4()))
        t = Process(target=run_schedule)
        t.start()
        return "timer on with interval:{}sec\n".format(nsec)
    elif status=='off' and t:
        if t:
            t.terminate()
            t = None
            schedule.clear()
        return "timer off\n"
    return "timer status not changed\n"

if __name__ == '__main__':
    app.run(host='0.0.0.0', port=5000)

You test this by just issuing:

$ curl http://127.0.0.1:5000/timer/on
timer on with interval:10sec
$ curl http://127.0.0.1:5000/timer/on
timer status not changed
$ curl http://127.0.0.1:5000/timer/off
timer off
$ curl http://127.0.0.1:5000/timer/off
timer status not changed

Every 10sec the timer is on it will issue a timer message to console:

127.0.0.1 - - [18/Sep/2018 21:20:14] "GET /timer/on HTTP/1.1" 200 -
timer job id=b64ed165-911f-4b47-beed-0d023ead0a33
timer: 10.0117sec
timer job id=b64ed165-911f-4b47-beed-0d023ead0a33
timer: 10.0102sec

Answer

/[\W\S_]/

Explanation

This creates a character class removing the word characters, space characters, and adding back the underscore character (as underscore is a "word" character). All that is left is the special characters. Capital letters represent the negation of their lowercase counterparts.

\W will select all non "word" characters equivalent to [^a-zA-Z0-9_]
\S will select all non "whitespace" characters equivalent to [ \t\n\r\f\v]
_ will select "_" because we negate it when using the \W and need to add it back in

In my case I had special instruction into nginx configuration file:

location ~ \.(js|css|png|jpg|gif|swf|ico|pdf|mov|fla|zip|rar)$ {
            try_files $uri =404;
    }

All clients have received '404' because nginx nothing known about Flask.

I hope it help someone.

At first make sure you have mysql installed properly. You can ensure it just by checking that whether you can access mysql using mysql command promp. So if you mysql is working then probably it is not loading. For that follow the steps given below

First of all, you must find your php.ini. It could be anywhere but if you create a small php file with the

<?php phpinfo(); ?>

script it will tell you where it is. Just look at the path of loaded configuration file. Common places include /etc/apache/, /etc/php4/apache2/php.ini, /etc/php5/apache2/php.ini or even /usr/local/lib/php.ini for Windows it may be C:\Users\username\PHP\php.ini

Edit your server’s php.ini and look for the following line. Remove the ‘;’ from the start of the line and restart Apache. Things should work fine now!

;extension=mysql.so

should become

extension=mysql.so

For windows it will be

;extension=mysql.dll

should become

extension=mysql.dll

Vue allows for you to specify a default prop value and type directly, by making props an object (see: https://vuejs.org/guide/components.html#Prop-Validation):

props: {
  year: {
    default: 2016,
    type: Number
  }
}

If the wrong type is passed then it throws an error and logs it in the console, here's the fiddle:

https://jsfiddle.net/cexbqe2q/

In Spyder 2.3.8 on Ubuntu, I found several settings to do this - each one for a different part of the window... Seems that you can't make all areas dark though.

And the final result looks like this:

Bootstrap Modal Events:

1. hide.bs.modal => Occurs when the modal is about to be hidden.
2. hidden.bs.modal => Occurs when the modal is fully hidden (after CSS transitions have completed).

<script type="text/javascript">
    $("#salesitems_modal").on('hide.bs.modal', function () {
        //actions you want to perform after modal is closed.
    });
</script>

I hope this will Help.

this is supported from version hive 0.14

INSERT INTO TABLE pd_temp(dept,make,cost,id,asmb_city,asmb_ct,retail) VALUES('production','thailand',10,99202,'northcarolina','usa',20)

Allocate memory before using the pointer. If you don't allocate memory *point = 12 is undefined behavior.

int *fun()
{
    int *point = malloc(sizeof *point); /* Mandatory. */
    *point=12;  
    return point;
}

Also your printf is wrong. You need to dereference (*) the pointer.

printf("%d", *ptr);
             ^

Mine was more of a mistake, what happened was loop click(i guess) basically by clicking on the login the parent was also clicked which ended up causing Maximum call stack size exceeded.

$('.clickhere').click(function(){
   $('.login').click();
});

<li class="clickhere">
  <a href="#" class="login">login</a>
</li>

Go to your Postgresql Config and Edit pg_hba.conf

sudo vim /etc/postgresql/9.3/main/pg_hba.conf

Then Change this Line :

Database administrative login by Unix domain socket
local      all              postgres                                md5

to :

Database administrative login by Unix domain socket
local   all             postgres                                peer

then Restart the PostgreSQL service via SUDO command then

psql -U postgres

You will be now entered and will See the Postgresql terminal

then enter

\password

and enter the NEW Password for Postgres default user, After Successfully changing the Password again go to the pg_hba.conf and revert the change to "md5"

now you will be logged in as

psql -U postgres

with your new Password.

Let me know if you all find any issue in it.

I wrote a video capture software, similar to FRAPS for DirectX applications. The source code is available and my article explains the general technique. Look at http://blog.nektra.com/main/2013/07/23/instrumenting-direct3d-applications-to-capture-video-and-calculate-frames-per-second/

Respect to your questions related to performance,

• DirectX should be faster than GDI except when you are reading from the frontbuffer which is very slow. My approach is similar to FRAPS (reading from backbuffer). I intercept a set of methods from Direct3D interfaces.

• For video recording in realtime (with minimal application impact), a fast codec is essential. FRAPS uses it's own lossless video codec. Lagarith and HUFFYUV are generic lossless video codecs designed for realtime applications. You should look at them if you want to output video files.

• Another approach to recording screencasts could be to write a Mirror Driver. According to Wikipedia: When video mirroring is active, each time the system draws to the primary video device at a location inside the mirrored area, a copy of the draw operation is executed on the mirrored video device in real-time. See mirror drivers at MSDN: http://msdn.microsoft.com/en-us/library/windows/hardware/ff568315(v=vs.85).aspx.

String str = "Hello   World";
String res[] = str.split("\\s+");

It will be proxy configuration of your browser. In NetWork Setting, use no proxy

For Manual proxy configuration add exception(No Proxy for in Firefox) like localhost:8080, localhost.

For eslint:

"editor.codeActionsOnSave": { "source.fixAll.eslint": true }

Try the following:

$ch = curl_init("http://www.example-webpage.com/file.html");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
$content = curl_exec($ch);
curl_close($ch);

I would only recommend this for small files. Big files are read as a whole and are likely to produce a memory error.

EDIT: after some discussion in the comments we found out that the problem was that the server couldn't resolve the host name and the page was in addition a HTTPS resource so here comes your temporary solution (until your server admin fixes the name resolving).

what i did is just pinging graph.facebook.com to see the IP address, replace the host name with the IP address and instead specify the header manually. This however renders the SSL certificate invalid so we have to suppress peer verification.

//$url = "https://graph.facebook.com/19165649929?fields=name";
$url = "https://66.220.146.224/19165649929?fields=name";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Host: graph.facebook.com'));
$output = curl_exec($ch);
curl_close($ch); 

Keep in mind that the IP address might change and this is an error source. you should also do some error handling using curl_error();.

Specifying auto on width and height elements is the same as removing them, technically. Using vanilla Javascript:

images[i].style.height = "auto";
images[i].style.width = "auto";

Use %0A (URL encoding) instead of \n (C encoding).

I know this is an old question but I find that the answers are not sufficent enough

The cleanest way to do this is to use this code

$(".myRadio").click(function() {
alert($(this).val());   
});

:-)

Your form input data should look like this

<input type="radio" value="40000" name="pay"  class="myRadio" />
<label for="40000">40000</label>

Try putting it in quotes:

find . -name '*test.c'

In some cases, it's easily to deal with a null than an exception. In particular, the coalescing operator is handy:

SomeClass someObject = (obj as SomeClass) ?? new SomeClass();

It also simplifies code where you are (not using polymorphism, and) branching based on the type of an object:

ClassA a;
ClassB b;
if ((a = obj as ClassA) != null)
{
    // use a
}
else if ((b = obj as ClassB) != null)
{
    // use b
}

As specified on the MSDN page, the as operator is equivalent to:

expression is type ? (type)expression : (type)null

which avoids the exception completely in favour of a faster type test, but also limits its use to types that support null (reference types and Nullable<T>).

In Swift both 3&4

 func removeImageLocalPath(localPathName:String) {
            let filemanager = FileManager.default
            let documentsPath = NSSearchPathForDirectoriesInDomains(.documentDirectory,.userDomainMask,true)[0] as NSString
            let destinationPath = documentsPath.appendingPathComponent(localPathName)
 do {
        try filemanager.removeItem(atPath: destinationPath)
        print("Local path removed successfully")
    } catch let error as NSError {
        print("------Error",error.debugDescription)
    }
    }

or This method can delete all local file

func deletingLocalCacheAttachments(){
        let fileManager = FileManager.default
        let documentsURL = fileManager.urls(for: .documentDirectory, in: .userDomainMask)[0]
        do {
            let fileURLs = try fileManager.contentsOfDirectory(at: documentsURL, includingPropertiesForKeys: nil)
            if fileURLs.count > 0{
                for fileURL in fileURLs {
                    try fileManager.removeItem(at: fileURL)
                }
            }
        } catch {
            print("Error while enumerating files \(documentsURL.path): \(error.localizedDescription)")
        }
    }

You can use simple color resources, specified usually inside res/values/colors.xml.

<color name="red">#ffff0000</color>

and use this via android:background="@color/red". This color can be used anywhere else too, e.g. as a text color. Reference it in XML the same way, or get it in code via getResources().getColor(R.color.red).

You can also use any drawable resource as a background, use android:background="@drawable/mydrawable" for this (that means 9patch drawables, normal bitmaps, shape drawables, ..).

use -Wno-reorder (man gcc is your friend :) )

Calendar cal = Calendar.getInstance();
cal.add(Calendar.DATE, 7);
Date date = c.getTime();
SimpleDateFormat ft = new SimpleDateFormat("MM-dd-YYYY");
JOptionPane.showMessageDialog(null, ft.format(date));

This will display your date + 7 days in month, day and year format in a JOption window pane.

The best answer resides in the Angular GitHub discussion (Changing route doesn't scroll to top in the new page).

Maybe you want go to top only in root router changes (not in children, because you can load routes with lazy load in f.e. a tabset)

app.component.html

<router-outlet (deactivate)="onDeactivate()"></router-outlet>

app.component.ts

onDeactivate() {
  document.body.scrollTop = 0;
  // Alternatively, you can scroll to top by using this other call:
  // window.scrollTo(0, 0)
}

I know, this is an old question, but couldn't find the solution here. After some tries, I found out, that some added "<asp:UpdatePanel" had been the reason.

After (re)moving them, all works fine like before.

Classloaders can be a tricky problem. You can especially run into problems if you're using multiple classloaders and don't have their interactions clearly and rigorously defined. I think in order to actually be able to unload a class youlre going go have to remove all references to any classes(and their instances) you're trying to unload.

Most people needing to do this type of thing end up using OSGi. OSGi is really powerful and surprisingly lightweight and easy to use,

You can disable expandtab option from within Vim as below:

:set expandtab!

or

:set noet

PS: And set it back when you are done with inserting tab, with "set expandtab" or "set et"

PS: If you have tab set equivalent to 4 spaces in .vimrc (softtabstop), you may also like to set it to 8 spaces in order to be able to insert a tab by pressing tab key once instead of twice (set softtabstop=8).

UPDATE 2017

Better documentation is now available and you can use both JSON and JavaScript based configurations: angular-cli documentation proxy

sample https proxy configuration

{
  "/angular": {
     "target":  {
       "host": "github.com",
       "protocol": "https:",
       "port": 443
     },
     "secure": false,
     "changeOrigin": true,
     "logLevel": "info"
  }
}

To my knowledge with Angular 2.0 release setting up proxies using .ember-cli file is not recommended. official way is like below

1. edit "start" of your package.json to look below

   "start": "ng serve --proxy-config proxy.conf.json",

2. create a new file called proxy.conf.json in the root of the project and inside of that define your proxies like below

   {
     "/api": {
       "target": "http://api.yourdomai.com",
       "secure": false
     }
   }
   

3. Important thing is that you use npm start instead of ng serve

If you have more then 1 dimension array

with open("file.txt", 'w') as output:
    for row in values:
        output.write(str(row) + '\n')

Code to write without '[' and ']'

with open("file.txt", 'w') as file:
        for row in values:
            s = " ".join(map(str, row))
            file.write(s+'\n')

Make sure you import MaterialModule as well since you are using md-input which does not belong to FormsModule

In my case, it was neither systemd nor a cron job, but it was snap. So I had to run:

sudo snap stop docker
sudo snap remove docker

... and the last command actually never ended, I don't know why: this snap thing is really a pain. So I also ran:

sudo apt purge snap

:-)

This might work for you:

printf "{new\nto\nlinux}" | paste -sd' '            
{new to linux}

or:

printf "{new\nto\nlinux}" | tr '\n' ' '            
{new to linux}

or:

printf "{new\nto\nlinux}" |sed -e ':a' -e '$!{' -e 'N' -e 'ba' -e '}' -e 's/\n/ /g'
{new to linux}

You can make view of the table with specifit records and then dump sql file

CREATE VIEW foo AS
SELECT id,name,city FROM nyummy.cimory WHERE city = 'tokyo'

Remove existing origin and add new origin to your project directory

>$ git remote show origin

>$ git remote rm origin

>$ git add .

>$ git commit -m "First commit"

>$ git remote add origin Copied_origin_url

>$ git remote show origin

>$ git push origin master

This goes back to the basic difference between & and &&, | and ||

BTW you perform the same tasks many times. Not sure if efficiency is an issue. You could remove some of the duplication.

Z z2 = partialHits.get(req_nr).get(z); // assuming a value cannout be null.
Z z3 = tmpmap.get(z); // assuming z3 cannot be null.
if(z2 == null || z2 < z3){   
    partialHits.get(z).put(z, z3);   
} 

only with this:

const a = true; const b = false;

console.log(+a);//1 console.log(+b);//0

If anyone else is on this question, when using include('somepath.php'); and that file contains a function, the var must be declared there as well. The inclusion of $var=$var; won't always work. Try running these:

one.php:

<?php
    $vars = array('stack','exchange','.com');

    include('two.php'); /*----- "paste" contents of two.php */

    testFunction(); /*----- execute imported function */
?>

two.php:

<?php
    function testFunction(){ 
        global $vars; /*----- vars declared inside func! */
        echo $vars[0].$vars[1].$vars[2];
    }
?>

Recently, I have faced this issue. And fixed it by changing CPU/ABI from Intel Atom (x86) to ARM(armeabi-v7a).

• Select the Virtual Device. Click on Edit
• Click on CPU/ABI option
• Change it to ARM(armeabi-v7a) from intel. Click OK

Job done.

Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off".

I think it depends on what problems you are facing.

1. shortest path on simple graph -> bfs
2. all possible results -> dfs
3. search on graph(treat tree, martix as a graph too) -> dfs ....

Put it this way

where ("R"."TIME_STAMP">=TO_DATE ('03-02-2013 00:00:00', 'DD-MM-YYYY HH24:MI:SS')
   AND "R"."TIME_STAMP"<=TO_DATE ('09-02-2013 23:59:59', 'DD-MM-YYYY HH24:MI:SS')) 

Where R is table name.
TIME_STAMP is FieldName in Table R.

since your form has a field called 'q', leaving it blank still sends an empty string.

try

if 'q' in request.GET and request.GET['q'] != "" :
     message
else
     error message

If you are asking if you can pair two devices without the user EVER approving the pairing, no it cannot be done, it is a security feature. If you are paired over Bluetooth there is no need to exchange data over NFC, just exchange data over the Bluetooth link.

I don't think you can circumvent Bluetooth security by passing an authentication packet over NFC, but I could be wrong.

You can always JQuery-ize your form.submit, but it may just call the same thing:

$("form").submit(); // probably able to affect multiple forms (good or bad)

// or you can address it by ID
$("#yourFormId").submit();

You can also attach functions to the submit event, but that is a different concept.

That should work even if one, and only one of the conditions is true :

var str = "bonjour le monde vive le javascript";
var arr = ['bonjour','europe', 'c++'];

function contains(target, pattern){
    var value = 0;
    pattern.forEach(function(word){
      value = value + target.includes(word);
    });
    return (value === 1)
}

console.log(contains(str, arr));

You can use ::after to create a 0px-height block after the <h4>, which effectively moves anything after the <h4> to the next line:

h4 {_x000D_
  display: inline;_x000D_
}_x000D_
h4::after {_x000D_
  content: "";_x000D_
  display: block;_x000D_
}

<ul>_x000D_
  <li>_x000D_
    Text, text, text, text, text. <h4>Sub header</h4>_x000D_
    Text, text, text, text, text._x000D_
  </li>_x000D_
</ul>

1. In the 'Solution Explorer' tree, expand the P2 project and then right-click the project and select 'Add Reference' from the menu.
2. On the 'Add Reference' dialog, select the 'Projects' tab and select your P1 project.
3. If you are using namespaces then you will need to import the namespaces for your P1 types by adding 'using' statements to your files in P2.

Note that the types in P1 that you wish to access directly must have a sufficient access level: typically this means they must be made public.

A Date object's underlying value is actually in UTC. To prove this, notice that if you type new Date(0) you'll see something like: Wed Dec 31 1969 16:00:00 GMT-0800 (PST). 0 is treated as 0 in GMT, but .toString() method shows the local time.

Big note, UTC stands for Universal time code. The current time right now in 2 different places is the same UTC, but the output can be formatted differently.

What we need here is some formatting

var _date = new Date(1270544790922); 
// outputs > "Tue Apr 06 2010 02:06:30 GMT-0700 (PDT)", for me
_date.toLocaleString('fi-FI', { timeZone: 'Europe/Helsinki' });
// outputs > "6.4.2010 klo 12.06.30"
_date.toLocaleString('en-US', { timeZone: 'Europe/Helsinki' });
// outputs > "4/6/2010, 12:06:30 PM"

This works but.... you can't really use any of the other date methods for your purposes since they describe the user's timezone. What you want is a date object that's related to the Helsinki timezone. Your options at this point are to use some 3rd party library (I recommend this), or hack-up the date object so you can use most of it's methods.

Option 1 - a 3rd party like moment-timezone

moment(1270544790922).tz('Europe/Helsinki').format('YYYY-MM-DD HH:mm:ss')
// outputs > 2010-04-06 12:06:30
moment(1270544790922).tz('Europe/Helsinki').hour()
// outputs > 12

This looks a lot more elegant than what we're about to do next.

Option 2 - Hack up the date object

var currentHelsinkiHoursOffset = 2; // sometimes it is 3
var date = new Date(1270544790922);
var helsenkiOffset = currentHelsinkiHoursOffset*60*60000;
var userOffset = _date.getTimezoneOffset()*60000; // [min*60000 = ms]
var helsenkiTime = new Date(date.getTime()+ helsenkiOffset + userOffset);
// Outputs > Tue Apr 06 2010 12:06:30 GMT-0700 (PDT)

It still thinks it's GMT-0700 (PDT), but if you don't stare too hard you may be able to mistake that for a date object that's useful for your purposes.

I conveniently skipped a part. You need to be able to define currentHelsinkiOffset. If you can use date.getTimezoneOffset() on the server side, or just use some if statements to describe when the time zone changes will occur, that should solve your problem.

Conclusion - I think especially for this purpose you should use a date library like moment-timezone.

When you cherry-pick, it creates a new commit with a new SHA. If you do:

git cherry-pick -x <sha>

then at least you'll get the commit message from the original commit appended to your new commit, along with the original SHA, which is very useful for tracking cherry-picks.

An easier and more standard way to simulate a mouse click would be directly using the event constructor to create an event and dispatch it.

Though the MouseEvent.initMouseEvent() method is kept for backward compatibility, creating of a MouseEvent object should be done using the MouseEvent() constructor.

var evt = new MouseEvent("click", {
    view: window,
    bubbles: true,
    cancelable: true,
    clientX: 20,
    /* whatever properties you want to give it */
});
targetElement.dispatchEvent(evt);

Demo: http://jsfiddle.net/DerekL/932wyok6/

This works on all modern browsers. For old browsers including IE, MouseEvent.initMouseEvent will have to be used unfortunately though it's deprecated.

var evt = document.createEvent("MouseEvents");
evt.initMouseEvent("click", canBubble, cancelable, view,
                   detail, screenX, screenY, clientX, clientY,
                   ctrlKey, altKey, shiftKey, metaKey,
                   button, relatedTarget);
targetElement.dispatchEvent(evt);

Convert to seconds those strings:

var str1 = '10:20:45';
var str2 = '5:10:10';

str1 =  str1.split(':');
str2 =  str2.split(':');

totalSeconds1 = parseInt(str1[0] * 3600 + str1[1] * 60 + str1[0]);
totalSeconds2 = parseInt(str2[0] * 3600 + str2[1] * 60 + str2[0]);

// compare them

if (totalSeconds1 > totalSeconds2 ) { // etc...

To ask permission for the photo app you need to add this code (Swift 3):

PHPhotoLibrary.requestAuthorization({ 
       (newStatus) in 
         if newStatus ==  PHAuthorizationStatus.authorized { 
          /* do stuff here */ 
    } 
})

If you identify a page that takes time to load, use SharePoint's Developer Dashboard to see which component takes time.

First you need to create a mock m_contractsDao and set it up. Assuming that the class is ContractsDao:

ContractsDao mock_contractsDao = mock(ContractsDao.class);
when(mock_contractsDao.save(any(String.class))).thenReturn("Some result");

Then inject the mock into m_orderSvc and call your method.

m_orderSvc.m_contractsDao = mock_contractsDao;
m_prog = new ProcessOrdersWorker(m_orderSvc, m_opportunitySvc, m_myprojectOrgSvc);
m_prog.work(); 

Finally, verify that the mock was called properly:

verify(mock_contractsDao, times(1)).save("Parameter I'm expecting");

Just add the function reference to the $scope in the controller:

for example if you want the function MyFunction to work in ng-click just add to the controller:

app.controller("MyController", ["$scope", function($scope) {
   $scope.MyFunction = MyFunction;
}]);

If you want implications, in some scenarios Google Chrome performance is horrible with hardware acceleration enabled. Oddly enough, changing the "trick" to -webkit-transform: rotateZ(360deg); worked just fine.

I don't believe we ever figured out why.

Update On 18-Dec-2017

You can update Google Play Services via the Play Store app in your emulator just as you would on a physical Android device from API 24.

check Emulator new features added with stable update from Android Studio v 3.0

Google Play Support - From Google : We know that many app developers use Google Play Services, and it can be difficult to keep the service up to date in the Android Emulator system images. To solve this problem, we now offer versions of Android System Images that include the Play Store app. The Google Play images are available starting with Android Nougat (API 24). With these new emulator images, you can update Google Play Services via the Play Store app in your emulator just as you would on a physical Android device. Plus, you can now test end-to-end install, update, and purchase flows with the Google Play Store.

Quick Boot - Quick Boot allows you to resume your Android Emulator session in under 6 seconds

Android CTS Compatibility

Performance Improvements - With the latest versions of the Android Emulator, we now allocate RAM on demand, instead of allocating and pinning the memory to the max RAM size defined in your AVD.

Virtual sensors

Wi-Fi support

GPS location and Many more...

I really like cdmckay's answer, but it does not really look good to check the size in a real time: it is just too slow (2 seconds for me). This is the improved version, which is way faster and more exact, also with an option to choose how big the error can be (default 250,000, the smaller error is - the longer the calculation is):

function getLocalStorageMaxSize(error) {
  if (localStorage) {
    var max = 10 * 1024 * 1024,
        i = 64,
        string1024 = '',
        string = '',
        // generate a random key
        testKey = 'size-test-' + Math.random().toString(),
        minimalFound = 0,
        error = error || 25e4;

    // fill a string with 1024 symbols / bytes    
    while (i--) string1024 += 1e16;

    i = max / 1024;

    // fill a string with 'max' amount of symbols / bytes    
    while (i--) string += string1024;

    i = max;

    // binary search implementation
    while (i > 1) {
      try {
        localStorage.setItem(testKey, string.substr(0, i));
        localStorage.removeItem(testKey);

        if (minimalFound < i - error) {
          minimalFound = i;
          i = i * 1.5;
        }
        else break;
      } catch (e) {
        localStorage.removeItem(testKey);
        i = minimalFound + (i - minimalFound) / 2;
      }
    }

    return minimalFound;
  }
}

To test:

console.log(getLocalStorageMaxSize()); // takes .3s
console.log(getLocalStorageMaxSize(.1)); // takes 2s, but way more exact

This works dramatically faster for the standard error; also it can be much more exact when necessary.

If you're using MySQL and want the database itself to perform the conversion, use this:

DATE_FORMAT(date,format)

If you prefer to format using Java, use this:

java.text.SimpleDateFormat

SimpleDateFormat dateFormat = new SimpleDateFormat("M/dd/yyyy");
dateFormat.format( new Date() );

Use this:

return JavaScript(alert("Hello this is an alert"));

or:

return Content("<script language='javascript' type='text/javascript'>alert('Thanks for Feedback!');</script>");

I use a List of NameValuePair and URLEncodedUtils to create the url string I want.

protected String addLocationToUrl(String url){
    if(!url.endsWith("?"))
        url += "?";

    List<NameValuePair> params = new LinkedList<NameValuePair>();

    if (lat != 0.0 && lon != 0.0){
        params.add(new BasicNameValuePair("lat", String.valueOf(lat)));
        params.add(new BasicNameValuePair("lon", String.valueOf(lon)));
    }

    if (address != null && address.getPostalCode() != null)
        params.add(new BasicNameValuePair("postalCode", address.getPostalCode()));
    if (address != null && address.getCountryCode() != null)
        params.add(new BasicNameValuePair("country",address.getCountryCode()));

    params.add(new BasicNameValuePair("user", agent.uniqueId));

    String paramString = URLEncodedUtils.format(params, "utf-8");

    url += paramString;
    return url;
}

You can use the pg_typeof() function, which also works well for arbitrary values.

SELECT pg_typeof("stu_id"), pg_typeof(100) from student_details limit 1;

For me this issue occured when I was running python while within my site-packages folder. If I ran it anywhere else, it was no longer an issue.

You need to examine (put a breakpoint on / Quick Watch) the Request object in the Page_Load method of your Test.aspx.cs file.

For very large matrices using sum(sum(A)) can be faster than sum(A(:)):

>> A = rand(20000);
>> tic; B=sum(A(:)); toc; tic; C=sum(sum(A)); toc
Elapsed time is 0.407980 seconds.

I had this problem in a unit test which opened a lot of connections to the DB via a connection pool and then "stopped" the connection pool (ManagedDataSource actually) to release the connections at the end of the each test. I always ran out of connections at some point in the suite of tests.

Added a Thread.sleep(500) in the teardown() of my tests and this resolved the issue. I think that what was happening was that the connection pool stop() releases the active connections in another thread so that if the main thread keeps running tests the cleanup thread(s) got so far behind that the Oracle server ran out of connections. Adding the sleep allows the background threads to release the pooled connections.

This is much less of an issue in the real world because the DB servers are much bigger and there is a healthy mix of operations (not just endless DB connect/disconnect operations).

To remove everything before the first /

input = input.Substring(input.IndexOf("/"));

To remove everything after the first /

input = input.Substring(0, input.IndexOf("/") + 1);

To remove everything before the last /

input = input.Substring(input.LastIndexOf("/"));

To remove everything after the last /

input = input.Substring(0, input.LastIndexOf("/") + 1);

An even more simpler solution for removing characters after a specified char is to use the String.Remove() method as follows:

To remove everything after the first /

input = input.Remove(input.IndexOf("/") + 1);

To remove everything after the last /

input = input.Remove(input.LastIndexOf("/") + 1);

Integer.decode

You can also use public static Integer decode(String nm) throws NumberFormatException.

It also works for base 8 and 16:

// base 10
Integer.parseInt("12");     // 12 - int
Integer.valueOf("12");      // 12 - Integer
Integer.decode("12");       // 12 - Integer
// base 8
// 10 (0,1,...,7,10,11,12)
Integer.parseInt("12", 8);  // 10 - int
Integer.valueOf("12", 8);   // 10 - Integer
Integer.decode("012");      // 10 - Integer
// base 16
// 18 (0,1,...,F,10,11,12)
Integer.parseInt("12",16);  // 18 - int
Integer.valueOf("12",16);   // 18 - Integer
Integer.decode("#12");      // 18 - Integer
Integer.decode("0x12");     // 18 - Integer
Integer.decode("0X12");     // 18 - Integer
// base 2
Integer.parseInt("11",2);   // 3 - int
Integer.valueOf("11",2);    // 3 - Integer

If you want to get int instead of Integer you can use:

1. Unboxing:

   int val = Integer.decode("12"); 
   

2. intValue():

   Integer.decode("12").intValue();
   

The onunload event won't fire if the onload event did not fire. Unfortunately the onload event waits for all binary content (e.g. images) to load, and inline scripts run before the onload event fires. DOMContentLoaded fires when the page is visible, before onload does. And it is now standard in HTML 5, and you can test for browser support but note this requires the <!DOCTYPE html> (at least in Chrome). However, I can not find a corresponding event for unloading the DOM. And such a hypothetical event might not work because some browsers may keep the DOM around to perform the "restore tab" feature.

The only potential solution I found so far is the Page Visibility API, which appears to require the <!DOCTYPE html>.

You want to do more than just getState. You want to react to changes in the store.

If you aren't using react-redux, you can do this:

function rerender() {
    const state = store.getState();
    render(
        <div>
            { state.items.map((item) => <p> {item.title} </p> )}
        </div>,
        document.getElementById('app')
    );
}

// subscribe to store
store.subscribe(rerender);

// do initial render
rerender();

// dispatch more actions and view will update

But better is to use react-redux. In this case you use the Provider like you mentioned, but then use connect to connect your component to the store.

It depends on the specific use case.

If your table is static and only has a short list of values (and there is just a small chance that this would change during a lifetime of DB), I would recommend this construction:

CREATE TABLE Foo 
(
    FooCode VARCHAR(16), -- short code or shortcut, but with some meaning.
    Name NVARCHAR(128), -- full name of entity, can be used as fallback in case when your localization for some language doesn't exist
    LocalizationCode AS ('Foo.' + FooCode) -- This could be a code for your localization table... 
)

Of course, when your table is not static at all, using INT as primary key is the best solution.

You were on the right track with response.getOutputStream(), but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:

@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
    // convert JSON to Employee 
    Employee emp = convertSomehow(json);

    // generate the file
    PdfUtil.showHelp(emp);

    // retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
    byte[] contents = (...);

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_PDF);
    // Here you have to set the actual filename of your pdf
    String filename = "output.pdf";
    headers.setContentDispositionFormData(filename, filename);
    headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
    ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
    return response;
}

Notes:

• use meaningful names for your methods: naming a method that writes a PDF document showHelp is not a good idea
• reading a file into a byte[]: example here
• I'd suggest adding a random string to the temporary PDF file name inside showHelp() to avoid overwriting the file if two users send a request at the same time

Based on unlimit's post on How to properly split a CSV using C# split() function? :

string[] tokens = System.Text.RegularExpressions.Regex.Split(paramString, ",");

NOTE: this doesn't handle escaped / nested commas, etc., and therefore is only suitable for certain simple CSV lists.

What is a singleton :
It is a class which only allows one instance of itself to be created, and usually gives simple access to that instance.

When should you use :
It depends on the situation.

Note : please do not use on db connection, for a detailed answer please refer to the answer of @Chad Grant

Here is a simple example of a Singleton:

public sealed class Singleton
{
    private static readonly Singleton instance = new Singleton();

    // Explicit static constructor to tell C# compiler
    // not to mark type as beforefieldinit
    static Singleton()
    {
    }

    private Singleton()
    {
    }

    public static Singleton Instance
    {
        get
        {
            return instance;
        }
    }
}

You can also use Lazy<T> to create your Singleton.

See here for a more detailed example using Lazy<T>

Try doing this using GNU sed:

sed '/CLIENTSCRIPT="foo"/a CLIENTSCRIPT2="hello"' file

if you want to substitute in-place, use

sed -i '/CLIENTSCRIPT="foo"/a CLIENTSCRIPT2="hello"' file

Output

CLIENTSCRIPT="foo"
CLIENTSCRIPT2="hello"
CLIENTFILE="bar"
